Similar reference characters on theditferent figures of the drawings indicate corresponding elements or features of construcat its lower end with a drill socket 4, a bevel gear wheel 5 being provided for rotating the spindle and driven by anothersuitably supported bevel gear wheel 6 suitably provided with a hand crank ,7. In carrying out the objects of the invention a spindle 8 is .provided which is removably secured in the socketlt and has a squared end portion 9 adapted to be inserted into a socket for driving the tire-bolting appliance. The drillpress includes an arm 10 which is adjustably secured to the column 2 for supporting work under the drill. For the purpose of clearly describing the function of thevinvention a wheel telly l1 is illustrated and is Vprovided with a tire 12 which is secured to the telly by means of bolts 13, having each a flush head 14 sunk into the tire, and a nut l5 on the end portion of the bolt. In some ico l cases the arm 10 has an aperture 16 therein adapted to receive bolts for securing work to the arm or for securing a table upon th arm.

The invention as preferably constructed comprises a bed-plate comprising a base portion 17 and a gear frame portion 18, the bedplate having a plane-faced under side adapted to rest either upon the top vof thearm 10 or'upon any other flat top support which may be suitable for the purpose. The under side of the base portion has a longitudinally extending recess 19 therein from which a longitudinal slot 2O extends to the top of the base portion, said top having two longitudinally extending guide ribs 21 and 22 on the edge portions thereof. A clamp bolt 23 is provided which'has a squared portion 24 adapted tofit slidingly in the slot 20, the bolt'having a head 25 adapted to enter the recess 19 and engage the under side of ythe base portion, the bolt being provided also V with a nut 26 on its upper end portion. A

head block 27 is provided which is adjustably seated upon the base portion and guided Y between the ribs 21 and 22, a suitable number of filling plates orshims 28`and 29 being placedon opposite sides of the head block, and they may be of different thicknesses. The head block has'an aperture 30A through which the bolt 23 extends so that the head block is adjustably secured upon the base portion 17. The head block is provided witli horizontal bolts 31 and 32 which extend through the filling plates. Two

- spring steel clamp plates are provided which have straight portions 33 and 34 respectively that are placed on the outer sides of the filling plates or shims and receive the bolts 31 and 32 whereby all are rigidly secured to the head block 27, the clamp plates comprising curved portions 35 and 36 respectively that embrace the column 2 for securing the appliance to the drill-press. rI`he thickness of the filling plates 28 and 29 usually depends upon the diameter of the column 2 so as to properly space the clamp plates apart to conform to the size of the column. Preferably the clamp plates are provided also with a binding bolt 37 arranged near the column in order to draw and firmly hold the plates to the column. In some cases the bolt 23 obviously may be sufliciently longto extend through the aperture 16 in the arm 10,5or a similar bolt may be placed in the aperture so as to extend through the slot 20 whereby to assist the clamp plates in holding the bed-plate securely on the arm 10;

or in such case the clamp plates might be dispensed with.

The gear frame portion 18 of the bedplate has two posts 38 and 39 thereon pro-V vided with bolt holes 40 and 41 respectively that extend through the bed plate, and it has also two journal bearings 42 and 43 ar- `an opening 67 therein.

57 projecting through the'fmember V44 and having a squared socket 53V therein to receive the squared portion 9-of the spindle 8 whereby to drive the wheel. A` Y. hollow gear wheel V59 is arrangedY also inthe gear housing (in mesh with thewheel'55 and 'it has a hollowv journal 60 that` is rotatably mounted in the portion 18', there being a` rotatably mounted in the frame member 44 and is counterbored to form a socket portion 63, therwall ofthe socket portion having recesses 64 and 65. therein adapted to re-,A

vceive a shank portion 66 of a socket -wrench which is provided, the shank portion having The wrench has a head portion 63k that projects beyond the, i

socket portion 62 of the wheel and has a suitable aperture 69 therein that extends to the opening 67 to permitthe passage of nuts through the wrench. The aperture 69 may be squared or of other contour to correspond to the square nut commonly used on tire-bolts, or to correspond `to the contourV i of other forms and to various sizes of nuts. The'socket wrench is provided with proj ec'- tions 70 and 71 that extend into'tlie recesses Y 64 and 65 respectively for preventingrota-V tion of the wrench and permitting it to beV readily removed and replaced by one of different size or shape.

ln order to prevent the bolts 13 'from,turn-, ing in the wheel fellv whenturnin'g the nuts thereon a bolt holder is provided which comprises a bar or lever 72 and a grip arm 73 which has a'curved finger 74 thereon, and also a shoulder 75 formed integrally with the bar and extending laterally from Vone end thereof, the fingerV being adapted to embrace the inner portion of the felly wh ile the lil-6,5147@ arm 73' extends adjacent to one side of the felly, the bar 'Z2 having a chisel-edge gouge 76 thereon in proximity to and extending approximately parallel tothe arm 73 so as to rest on top side of the head of the tirebolt. Y

lVhen the bed-plate is secured to the arm 10 of the drill press it is adjusted so that the spindle 8 when connected with the driving wheel 55 shall be in alinement with the spindle 3 of the drill-press and is secured in the socket t thereof, and it is evident that the spindle 3 may be elevated so as to draw the spindle 8 away from the socket 58 if desired, but whenproplerly connected therewith the spindle is rotated in the usual manner but is not fed downward as when drilling. l/Vhen applying a tire the bolts are inserted in place and the nuts placed by hand on the ends of the bolts, after which the felly is hung upon the upper end of the socket wrench so that the wrench receives the nut, and the drill-press being actuated in the proper direction the nut is quickly run on and tightened in the required position. The bolt holder is required only when the bolts are loose in the felly, or in case the nuts are so tight as to cause the bolts to turn. When the bolt holder is required the bar 72 is grasped in the hand of the operator, the curved finger 74 is readily hooked onto the felly and the gouge 7G pressed onto the head of the tire-bolt, the bar 72 being in such position that the operator may grasp the. inner side of the felly with his fingers and press down with his thumb over the bar with sufficient force to prevent turning of through the bore 6l ofthe gear wheel and thus escapel without *delaying operations. rlhe nuts obviously may be collected for future use if serviceable.
